We’ve upgraded the circuit boards in our Useless Machines to a new double-sided design.
The new version 1.2 boards have a spiffy blue solder mask and labeling of the parts is much better than the old boards.
Polarity of the LEDs was mistakenly left out of the silk-screen labeling, but other than that we are very happy with the new version.
With the new circuit boards are new Soldering Instructions. Please let us know if there are any mistakes or improvements we can to the instructions.
